  1. yes the metal shield is easily removed even with side cutters. Try checking continuity from each edge connection pad to the chip pin. You may get lucky and find a bad solder joint. Kaboom is only 2K in size. a 2716 could be programmed but you have to add a 74ls04 to invert A12 to use as CE on the new chip. You also have to cut pad 20 free from 5V and ground it.
  2. Hey Draxxon, First great job. I am able to play so much more on my FB9. Two comments, I am on a poor internet connection, speeds rivaling dial up. Your zip files are not huge but even the 100M size tends to take most of an hour. Would it be reasonable to say that the file v7 could be a base line and then any new or changed files could be smaller update/addition packs that you add to the existing v7. Second, I produced Alien Greed 5 and the rom you have is one of Chris Read's early versions. I have not released the final version of the rom yet (actually it is up to Chris as he is the author). Leave what you have but call it Alien Greed 5 Proto or some such. Thanks, bah
  3. Hello all, Just wanted to mention that Shark Hunter and Nightmare are up for sale on 2600connection. Thanks to Tim at 2600connection for hosting the pages for these. http://www.2600connection.com/features/features.html
  4. read to the end. there is more than just a cable.
  5. "There's no SD card slot, but you can still do a simple hack to let you add more games: https://armchairarcade.com/perspectives/2019/10/21/atari-flashback-x-2019-upgrade-to-support-external-usb-drives/" Thanks Bill. This hack puts the X back on the table for me. I wasn't interested in a cosmetic upgrade without an sd card option but this might tip the scales to buy the X and mod it, especially with better paddle support.
  6. Do you know what is wrong with your Ballblazer? If the rom chip is bad, you can remove it and replace it with a socket so you can play eproms of other pokey games. There are instructions for this on the 7800 forum somewhere.
  7. Chris I like it. Plays well 32k I can put on most any original board, just needs a hex inverter like 4 k 2600 games. 48 k is not too hard but it won't fit on the base cartridge board.
  8. Just a few thoughts. David Crane would have known his code intimately. He probably would not have made a "sloppy hack" of his own game. There don't seem to be any known bugs that would have needed searching for at this time frame. Eproms were expensive yet the maker kept this for posterity rather than erasing it and using it for the next project. I think this would make sense if you were working to port Pitfall to other systems, after all when you finished the C-64, then there is the 5200, and the Intellivision and the.... Pure supposition only.
  9. Hi, Spacer should work. often the clip (what you called a speed nut) either breaks or deforms so it can slide up the shaft. on most I have seen there is a small groove and if the clip is not broken, you can just push it down until it gets into the groove again.
  10. Can anyone tell me anything about these 2 activision eprom carts. I am assuming they were for game development but I am looking to see if others have them or know the story behind them. Pitfall works but when I read the eprom there are 4 bits different from the released rom. If you miss-step on a crocodiles head and into his mouth, you still die but your body falls through into the underground. Kind of interesting but I am not sure if it is just bit rot or an actual bug from a pre-release rom. The second cart I assume is a bank switch cart but the top chip is not one I know and I don't have a game eprom to put in and see if something works. Thanks for any feedback.
  11. As Swami says. And you will have a digital pad which won't work with a few analog only games. Still looks neet.
  12. bah


  13. The supply of carts in the wild has dwindled for me but I still find groups of commons for around $4 each or under and I re-use the game pcb and metal dust cover. At this price it is hard to justify the new shell which will require a new pcb too. I also followed your path and drew up a new case in CAD and approached a local molder that had connections with Chinese tool makers. The costs were similar so I chose to not do it. Have you contacted 2600connection, (timdu on these forums)?
